ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 379.821, dated March20, 1888.

' Application filed June 15, 1887. Serial No. 241,331. (No model.)

To aZZ whom it may concern:

Be it known that I, MoRRIs SOHMUOKER, a resident of Lanark, in thecounty of Carroll and State of Illinois, have invented certain new anduseful Improvements in Attachments for CoruPlanters; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

The letters of reference in this specification indicate the same partsin all the figures of the accompanying drawings, in which Figure 1 is aside elevation of a portion of a planter, showing an ordinaryseed-receptacle and shoe with my devices attached. Fig. 2 showsthesamein plan afterarotation ofninety degrees to the right. Fig. 3 isan elevation looking to the left in Fig. 1. Fig. etis a view, partly insection, showing the construction of certain parts hereinafter referredto.

In the drawings, A B O D represent, respectively, the shoe,discharge-tube, seed-receptacle, and slide-bar of an ordinarycorn-planter, of whose frame S T are portions.

In the rear of the receptacle 0 is placed a box for containing thefertilizing material, and this material is discharged by the action of arod, D, connected to and moving in unison with the slide-bar D. Belowthe box is a case, G, communicating with the box and containing a wheel,G, having cups (Z, whose horizontal shaft is mounted in the side wallsof the case. Upon this shaft is fixed a ratchet-wheel, a, Fig. 3, withwhich engages alternately two spring-pawls, b c, fixed upon the innerfaces of a slot in the broadened end of the rod D, which forms a plate,F, to slide in guides F upon the wheel-case G. By means of thisengagement the movement of the bar D in either direction causes thecup-wheel to rotate from left to right, for as the rod passes back andforth the upper pawl engages the ratchet-wheel in its advance and pushesit from left to right, but springs outward and slips over the teeth onits return. At the same time the lower pawl springs outward and slipsover the teeth in advancing, but engages the ratchet and draws it in thesame direction-4. 6., from left to right-while moving in a contrarydirection. From the case G a tube, L L, passes downward and forward todeliver the fertilizer discharged by the cup-wheel between the wings ofthe shoe A, where it falls with the seed discharged from the receptacle0. As the fertilizer falls from the box E it does not pass directly tothe ground, but remains upon an inclined valve-plate, K, until the nextmovement of the cup-wheel reverses the position of the valve anddischargesit with or in point of time a little in advance of the seed,owing to the shortness of the distance through which it at last falls.The valve is centrally pivoted in the tube, and from its upper edge alug projects through a curved slot in the wall of the tube to engage thelower end of a lever, I, by which the valve is actuated. The lever I ispivoted at J upon the tube, and its upper end passes through an eye uponthe lower part of the plate F, which, by its reciprocation, thus carriesthe lever back and forth.

A clamp, M, is placed upon the rod D, near the box E, and to it isattached a rod, N, which passes horizontally through the box E, and hasthat part lying within the box bent into loops for agitating thefertilizer just over the wheel, thereby insuring perfect filling of thecups.

The entire fertilizer attachment is secured to the planter by bolts V,passing through the adjacent walls of the box E and seed-receptacle C,and it is adapted for attachment to any planter, whether or not thewalls of the seedreceptacle are vertical. The bars P, connecting theslide-bar D and rod D, are adjustable in length to facilitate attachmentto any slide bar. The tube L L is made in two telescopic sections, asindicated at W, in order that, whatever the height of the particularplanter to which it is attached, the fertilizer may be de livered verynear the ground, and scattering by wind be thus avoided.

What I claim is- 1. The combination, with a fertilizer-receptacleadapted for attachment to the seed-box of a corn-planter, of aperipherally-recessed vertical wheel whose upper side forms the bottomof said receptacle, a band passing from said receptacle to the lowerside of said wheel and closely fitting the recessed surface thereof, anda tube open at the top, extending downward from the lowest part of saidwheel, where by rotation of the wheel may deliver fixed qu antities offertilizer at intervals and through the lower end of said tube. Y

2. In combination with a fertilizer-receptacle adapted for attachment tothe seed-box of a corn-planter, aperipherally-recessed vertical Wheelthe upper portion of whose circumference forms the bottom of saidreceptacle, a tube extending downward and forward from the lowest pointof said wheel to a point between the wings of the planter-shoe, saidtube being provided with a valve near its lower eX tremity, aratchet-wheel connected rigidly to said vertical wheel, a slide-barbearing pawls adapted to rotate said ratchet-wheel in one i 5 directiononly, a pivoted lever connecting said slide-bar and said valve, andmeans for de- 'tachably connecting said slide-bar rigidly to MORRISsoHMUoKEa:
